Following the auction of four pink diamonds for more than US $1 million a carat in the last 15 months, Christies has announced that it will offer a 10.09 Fancy Vivid purplish-pink diamond at next month’s Magnificent Jewels sale in New York.
The cushion cut diamond is expected to sell for US$12 million to $15 million.
Rahul Kadakia, head of jewellery at Christie’s New York, said that in recent years prices for top-quality coloured diamonds have increased rapidly, driven by both collector demand and increasingly limited supply.
“Collector demand for large coloured diamonds has never been stronger, especially where pink diamonds of this size and quality are concerned,” he said.
“Fewer than 10 percent of all pink diamonds mined weigh more than 0.20 carats, and even fewer exhibit the exceptional colour saturation and brilliance of this exceptional gem.
“At Christie’s New York this past December, jewellery collectors competed for a 6.89 carat Fancy Vivid purplish-pink diamond, which ultimately sold for US$6.9 million or US$1 million per carat,” he said.
“This larger stone, with its richer, deeper hue of pink and electrifying purple tone is positioned to become one of this season’s top-selling diamonds.”
